Why is all this important? Because, by drawing energy from the road as it moves along, the train can use a battery that is only 20 percent as large and powerful as would otherwise be required. There's a serious cost reduction as well – with the cost shifted to installing the power strips into the road. Overall, the total cost for electric vehicles is about a third of what standalone electric vehicles cost. KAIST president Suh Nam-Pyo had high praise for the technology:
Thanks to Roy B. for the tip!The potential for application (of this technology to public transport systems) is limitless. I dare say this is one of the most significant technical gains in the 21st century.
